"In a survey of programming language use by TIOBE Software, an analysis company focusing on software quality," Vaughan-Nichols said, "they found that 'After more than 4 years C is back at position number 1 in the TIOBE index.' It's not that C has suddenly gained new developers: 'The scores for C have been pretty constant through the years, varying between the 15% and 20% market share for almost 10 years.' The real reason C's is back on top is because Java use has been declining."
